There are many ways to demonstrate that evolution is real.

For example:
- Fossil organisms arranged by age, each appearing as an updated version of the previous one.
- Similarities between living species, suggesting a common ancestor from long ago.

But these forms of evidence suggest that evolution takes an enormously long time to happen. Is this always true?

Evolution can occur over both long periods, as seen in fossil records, and rapidly, as demonstrated by examples like bacterial resistance to antibiotics.

Explanation:

Evolution and Timescale

Evolution indeed often appears to take an enormously long time, as evidenced by fossil records showing progression over millions of years. However, rapid evolution can occur in certain situations, such as with bacteria evolving resistance to antibiotics in just a few decades. These examples highlight that while evolution can be a slow process, it can also happen relatively quickly.
